CAUTION

1. This BNWAS can be switched ON/OFF or settings can be changed with password, therefore only

authorized person (captain) can change or switch ON/OFF the BNWAS.

2. Before operating the machinery, you must read and be fully aware of the safety signs and the

guidelines.

3. In case of machine breakdown due to the heat exposure or use of faulty power cable which can

cause a serious damage, is not covered by A/S.

4. Please do not disassemble the equipment since it is equipped with electric circuit that can be

only handled by experienced technician. Exposure of the display screen to the UV light may

cause life-shortening of the LCD. Avoid overheating LCD by adjusting the contrast except for

the extreme dark display. The problem caused by the overheating may not be solved after the

temperature has been cooled down

SIGN DESCRIPTION

The PCB used in this equipment is produced under protected

environment of electrostatic discharge.

This is because the most of the semiconductor equipment used

in the PCB can be damaged easily by the electrostatic discharge.

!

You must prevent from damaging the equipment when

operating, as it can be easily damaged by the electrostatic

discharge.

Only experienced technician must work on the circuit of the

equipment as it is sensitive to electrostatic discharge.

Disassemble of this equipment is only allowed to the

technician authorized by our company.

Cleaning of the display screen

The surface of the screen is coated with non-reflective material, therefore it is important to clean and

take meticulous care when cleaning. Please follow the instructions below.

Use the cleaning spray (same as computer monitor), microfiber. Fold the tissue or the microfiber

three times, and wet the edge of the fiber with the spray. Use your index finger to wipe the monitor.

The screen may get damaged if the tissue is not wet enough.

When you require technical assistance, please contact the nearest SAMYUNGENC Store or the A/S

center.

CHAPTER 1 ABOUT BNWAS

The purpose of a bridge navigational watch alarm system is to monitor the bridge activity and detect

operator disability which could lead to marine accidents. The system monitors awareness of the Watch

officer and automatically alerts the Master or another qualified person if for any reason watch officer

becomes incapable of performing watch officer’s duties. This purpose is achieved by series of indications

and alarm to alert first the watch officer and, if he is not responding, then to alert Master or another

qualified person. Additionally, the BNWAS provide the watch officer with means of calling for immediate

assistance if required. BNWAS must operate whenever heading or track control system is interlocking

unless prohibited by the captain.

Maritime Safety Committee (MSC) from IMO requires BNWAS that meets the new IMO performance

standard requirement.

Existing Vessel requires to install the equipment before the first inspection after the below date.

▷ Existing passenger ship and Vessels under 3000t: 1

st

JULY 2012.

▷ Existing vessels over 500t: 1

st

JULY 2013..

▷ Existing vessels over 150t: 1

st

July 2014.

New Vessel must install the equipment by:

▷ New Vessels over 150t, and vessels constructed after the 1

st

July 2011 must be equipped with

Bridge Navigational Watch Alarm System (BNWAS).

The equipment complies below standards.

 IMO A.694(17) : General desired term for vessel radio equipment and electronic navigational

support

 IMO A.830(19) : Code for alarm and command

 IMO MSC. 128(75) : Performance standard for BNWAS

 IMO MSC/Circ. 982 : Layout and guidelines for bridge equipment’s ergonomic standards

 IEC 62616 : Method to test the BNWAS’ technical characteristic

 IEC 60945 : Test method and result on marine navigation and radio communication

equipment

 IEC 62288 : Test method and result on marine navigation information display desired

terms

 IEC 61162 : Marine navigation and radio communication equipment system digital

interface

CHAPTER 2 OPERATION OF BNWAS

This BNW-50’s setting is only adjustable by using password, therefore only authorized person

(captain) can switch ON/OFF and change the setting of the system.

However, when BNWAS is active with alarm, mode setting is not adjustable.

2.1 OPERATIONAL MODES

2.1.1 MANUAL ON MODE

On this mode, BNW-50 operates constantly.

2.1.2 MANUAL OFF MODE

On this mode, BNW-50 does not operate under any circumstances.

2.1.3 AUTOMATIC MODE

On this mode, BNW-50 operates automatically whenever the ship's heading or track control system is

activated and inhibited when this system is not activated.

2.2.1 DORMANT PERIOD

Once operational, the alarm system remains dormant for a period of between 3 and 12 min.

At the end of this dormant period, the alarm system initiates a visual indication on the bridge.

10

2.2.2 VISUAL INDICATION

If not “RESET” during this dormant period (3~12 minutes), visual indication will be initiated for the next

15 seconds. This gives time to “RESET” before the 1st stage bridge audible alarm is initiated. The visual

indication initiated at the end of the dormant period will take the form of a flashing indication.

2.2.3 1ST STAGE BRIDGE AUDIBLE ALARM

If not “RESET”, the BNW-50 will additionally sound a 1st stage bridge audible alarm on the bridge 15

seconds after the visual indication is initiated. This audible alarm is installed on the bridge and must be

able to wake the watch officer. The visual indication and 1st stage bridge audible alarm will activate and

can be turned off by resetting the timer by inputting “RESET”.

2.2.4 2ND STAGE REMOTE AUDIBLE ALARM

If not “RESET”, the BNW-50 will additionally sound a 2nd stage remote audible alarm in the back-up

officer's and/or Master's location 15 seconds after the 1st stage bridge audible alarm is initiated. Visual

indication, 1st stage bridge audible alarm and 2nd stage remote audible alarm will activate and can be

turned off by resetting the timer by inputting “RESET”.

2.2.5 3RD STAGE REMOTE AUDIBLE ALARM

If not “RESET”, the BNW-50 will additionally sound a 3rd stage remote audible alarm at the locations of

further crew members capable of taking corrective actions 90 seconds after the 2nd stage remote

audible alarm is initiated. The delay between the 2nd and 3rd stage remote audible alarm may be set to

a longer value on installation, up to a maximum of 3 min, to allow sufficient time for the back-up officer

and/or Master to reach the bridge. Also, until “RESET” is inputted, all alarms stays activated.

2.3 RESET FUNCTION

The reset function shall, by a single operator action, cancel the visual indication and all audible alarms

and initiate a further dormant period. If the reset function is activated before the end of the dormant

period, the period shall be re-initiated to run for its full duration from the time of the reset.

BNW-50’s “RESET” can be inputted in the following ways.

 Manual way of using “RESET BUTTON” on the bridge.

 Automatic way of using ‘Motion sensor” that detects the movement on the bridge.

2.4 EMERGENCY CALL

BNW-50 has built-in emergency call function. If this button is pressed down, 2nd stage remote audible

alarm is immediately initiated, and if no action is taken then 3rd stage remote audible alarm will initiate.

Watch officer can call for help using this function if needed.
